Potash Soda Borate - Department of Energy

2013-11-8  3.1.2 Beneficiation Methods Potash (rock) The ore is dry-crushed by rod and ball mills to free the KCL (potassium chloride, or potash) and put into a brine similar to salt water. It is then ground into distinct particles of potash and salt, pumped into tanks, and agitated to wash the clay off the ore. After

How phosphate is mined and processed

2014-4-21  rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 5.5 and 7.2.
